Changes in Left Ventricular Mass and Cardiovascular Risk Factors after Kidney Transplantation.

Area of Science:

• Cardiology
• Nephrology
• Transplantation Medicine

Background:

• Left ventricular hypertrophy (LVH) is a major cause of sudden cardiac death and a common complication post-transplant.
• Limited data exists from India on cardiovascular changes after kidney transplantation.
• Assessing LVH and cardiac function is crucial for improving outcomes in renal transplant recipients.

Purpose of the Study:

• To investigate changes in left ventricular mass and cardiac function in kidney transplant recipients.
• To evaluate the impact of kidney transplantation on cardiovascular risk factors.
• To provide data from India on post-transplant cardiovascular changes.

Main Methods:

• Prospective observational study including kidney transplant recipients.
• Echocardiography and clinical/biochemical parameters measured pre-transplant, at 6 months, and 1 year.
• Analysis focused on left ventricular mass index, ejection fraction, and blood pressure control.

Main Results:

• Significant reduction in left ventricular mass index (LVMI) from 124.8 ± 39 to 102.2 ± 24.4 g/m² (P <0.001).
• Improvement in ejection fraction from 57.8 ± 7% to 60.1 ± 1.9% (P = 0.015) at six months.
• Significant improvements in hemoglobin, blood pressure control, and reduced need for antihypertensive medications.

Conclusions:

• Kidney transplantation leads to significant regression of left ventricular hypertrophy.
• Renal transplantation improves both systolic and diastolic cardiac function.
• Transplantation effectively ameliorates cardiovascular risk in kidney transplant recipients.
